That you can get good solder flow when hand soldering seems to indicate that the temperature of your solder pot is too low. Still, I'm uneasy that you see gold on the pads after passing the board across the solder pot. Gold is so thin with ENIG. So

I need help with how long do I need to bake out double sided PCB's that have been cleaned. The units will not be reworked but instead will be moved on to hand stuffing. I have looked in IPC CH-65B and J-STD-033C. I get information for parts if I am r

Hey guys, I'm new to this forum and registered to ask a question about PCB assembly cost. I was hoping to design a PCB that will be approximately 6" by 6" with about 1100 0805 SMD components on it. Half of them being resistors (3 different values) a

The low value will be 0.624uF. You have to factor it from the low tolerance (-10%). So: 0.9 x 0.92 (machine tolerance) x 0.91 x 0.91 x 0.91 (3 decade aging factor for X7R dielectric). We factor hours at the 3rd decade (10,000 hours), but you can

If they're 1 1/2 years old, they are definitely aged parts. Either send them back for newer or widen your tolerances on the ICT to compensate. You are at the 3rd decade now (10,000 hours) and you will need to compensate for this. These parts are n

My software can easily open a PCB CSV file so this is probably the easiest way for you to generate a file. The setups are remembered via a write to the registry, so you can go with a standard set of values to arrive at a very usable file without havi

Hi everybody This week I was creating a new program by means of saving a successfull existing one under a new name with "UTILITIES/Data Base Utilities/Select/Copy/Delete Board Program" on CC7.54, to seize useful parts without having to teach them aga

I'm in the market for some new (to me) pick and place equipment, and, could use some opinions. I'm a MyData guy by experience, and have recently been working on some older Philips machines. I'm comfortable on a MyData platform due to experience,

Thanks Rob for your meaningful advice. Instead of just a general average time per component, I think if we have 3 averages, 1 per "component group", we will gain significant accuracy in the cost model. For instance, a motherboard may have 2500+ R and

Hello, Manufacturing process with high moisture and humidity environments and long term storage will definitely see pop corning effects once high temperature from soldering and/or re-flow process. The moisture that has been adsorbed is likely the ro
